When we were young, my wife, Jean and I lived in an apartment along with a lot of other young couples. One of the other couples included a guy named Max who worked at the same company I did. Max was a big guy and in very good shape. He and his girlfriend became friendly with us and we attended some of their parties.
In the past, Jean had noticed that Max couldn't help stare at her large breasts. It sometimes made her uncomfortable, since he was obviously so intensely interested in her. I couldn't blame him, since Jean's breasts were magnificent. She had a voluptuous, Italian body with wide hips, shapely legs and ass, along with large, full breasts.
At one of their parties, Max asked us to stay until after all the other guests had left. At the time, we had no idea what he had in mind. Later that evening, it was just the four of us. His girlfriend was a very dark, petite woman, with a great shape although with small breasts.
As we continued drinking, and Max's girlfriend was being very flirtatious with me. She would lie on the floor on her tummy, facing me. She wore no bra, and her small breasts were on very clearly on display. I wasn't sure how much I was supposed to look, but the view was fantastic. As I looked, she smiled at me in a flirtatious way. She was being pretty obvious, but since I was so young and inexperienced, I wasn't sure what was going on.
My wife went to the bathroom but I didn't notice that Max was also missing. I found out later that he had followed her, and when she emerged, he confronted her. He stared at her breasts and stood over her, looking at her in a dominant, sexy way. She was intimidated, and looked uncomfortable enough that he eventually let her pass. We left shortly thereafter.
